본 발명은 구상흑연 주철 또는 회주철제 가로등주의 성형물 표면을 그라인딩 작업하여 덧살과 돌출부를 깎아내는 정리작업으로 표면을 다듬은 다음 세척실에 옮기고 가로등주를 회전시키면서 철,금속전용 부식억제제(상품명 Rust Veto 50)가 0.5~7중량% 혼합된 세척용수를 분사하여 세척하는 방법으로 이물질을 제거하기 때문에 가로등주 표면에 부착된 각종 이물질을 신속하고 깨끗하게 제거할 수 있고 세척단계에서 방청작용이 진행되어 수세단계에서의 부식위험을 방지할 수 있으며 이물질이 제거된 가로등주를 150~200℃의 가열 건조실에 투입하여 20~50분간 가열 건조시키므로서 주철제 가로등주의 표현과 주철 공극속에 잠재한 수분과 공기를 강제 제거하는 전처리작업을 할 수 있게 되고 가열건조 단계에서 가로등주의 체온이 100~150℃가 유지되어 예열을 할 수 있도록 된다.The present invention is to grind the surface of the molding of the spherical graphite cast iron or gray cast iron street lamps by trimming the surface of the extrudate and protrusions, and then to move to the cleaning room and rotate the street lamps, corrosion inhibitors for iron and metal (trade name Rust Veto 50). Removes foreign matters by spraying washing water mixed with 0.5 ~ 7% by weight, so that various foreign substances adhering to the surface of street lamp can be removed quickly and cleanly. It can prevent the danger, and put the street lamps with foreign substances removed into the heating drying room at 150 ~ 200 ℃ and heat them for 20 ~ 50 minutes to express the cast iron street lamps and pretreatment to remove potential moisture and air in the cast iron voids. Preheating is possible because the body temperature of street lamp is maintained at 100 ~ 150 ℃ It is to be.
이어서 탈이온수에 아연, 알미늄, 그리콜유, 실란, 에칠실리케이트, 트리에타놀을 일정비율 혼합하여 만든 아연,알미늄 복합피막 형성제에 가로등주를 디핑하거나 상기 아연 알미늄복합피막형성제를 분무기로 분무하여 일정두께로 도포하고 300~380℃에서 40~45분간 열처리하는 수단으로 8~20미크론 두께의 부식방지 피막을 형성하기 때문에 가로등주와 피막사이에 공극이 없는 피막형성이 이루어지고 본 발명의 부식방지 피막형성제의 사용으로 환원성을 높여 내부식성 피막형성을 견고하게 형성할 수 있고 이로인해 금속이 수소를 흡수하여 부서지는 현상(수소취성)을 방지할 수 있으며 산처리 공정이 없어서 제조단계에서의 폐수발생을 막아 친환경적 작업이 가능케 된다.Subsequently, dipping the lamppost into a zinc / aluminum composite film former made by mixing a predetermined ratio of zinc, aluminum, glycol oil, silane, ethyl silicate, and triethanol in deionized water or spraying the zinc aluminum composite film former with a sprayer Since it forms an anti-corrosion film with a thickness of 8 to 20 microns by means of a thickness and heat treatment at 300 to 380 ° C. for 40 to 45 minutes, the film is formed without voids between the street lamp and the film, and the anti-corrosion film is formed according to the present invention. It is possible to form a corrosion resistant film by increasing the reducibility by using the agent, which can prevent the metal from absorbing hydrogen and breaking (hydrogen embrittlement). Eco-friendly work is possible by preventing it.
그리고 가로등주 표면에 형성되는 내부식성피막 형성제는 액상이기 때문에 복합피막형성제에 가로등주를 디핑하여 도포하거나 아연 알미늄 피막형성제를 분무기로 분무하여 도포하므로 1차,2차의 도포단계를 통해 8~20미크론두께의 피막을 형성하지만 1차,2차 피막형성작업에서 8~20미크론의 피막형성이 이루어지지 않으면 3차 피막형성작업까지 실시할 수 있으므로 1차,2차 실시에 국한되는 것은 아니다.And since the anti-corrosive film forming agent formed on the surface of the street lamp is liquid, it is applied by dipping the street lamp to the composite film forming agent or by spraying a zinc aluminum film forming agent with an atomizer. If a 20 micron-thick film is formed, but the 8 to 20 micron film is not formed in the primary and secondary film forming operations, the third and third film forming operations can be performed.
이어서 부식방지 피막이 형성된 표면에 아크릴우레탄 도료를 도포하거나 폴리에스텔수지에 황산바륨을 혼합한 우레탄계 도료 중에서 선택한 피막형성제를 80~150미크론으로 도포하여 180~280℃를 유지하는 오븐실에서 30~60분간 열처리를 하여 방습방수 작용이 양호하고 견고한 피막층을 형성함으로써 습기에 안전하고 우천시 감전사고를 방지할 수 있는 안전한 피막을 형성할 수 있게 되며 방습방수강화피막층 외면에 투명아크릴우레탄 페인트를 40~80미크론 두께로 도포하여 마감함으로써 자외선 보호피막이 형성되어 이미 형성된 피막을 내구적으로 보호할 수 있게 된다.Next, apply an acrylic urethane paint on the surface where the anti-corrosion coating is formed or apply a film-forming agent selected from urethane-based paints in which barium sulfate is mixed with polyester resin at 80 to 150 microns to maintain 180 to 280 ° C. By heat-treatment for a minute, it has a good moisture-proof waterproofing effect and forms a solid coating layer, which makes it safe to moisture and prevents electric shock in case of rain, and makes transparent acrylic urethane paint 40 ~ 80 micron on the outer surface of the moisture-proof waterproof coating layer. By applying a thickness to finish the UV protective film is formed to be able to durablely protect the already formed film.
이와 같이 된 본 발명은 주철가로등주의 표면에 환경유해물질인 중금속이 발생되지 않는 내부식성 피막을 형성하여 친환경적이고 습기와 우수로 인한 감전사고를 방지할 수 있는 안전한 주철가로등주를 제조할 수 있게 된다.In this way, the present invention forms a corrosion resistant film in which heavy metals, which are environmentally harmful substances, are not generated on the surface of cast iron street lamps, thereby making it possible to manufacture safe cast iron street lamps that are environmentally friendly and prevent electric shock due to moisture and excellentness.
특히 본 발명은 아연, 알미늄 복합피막층을 조성할 때 탈이온수를 사용함으로써 아연용융도금 제조공정에서 발생하는 중금속 및 폐수의 발생요인을 근본적으로 차단했으며 주철 가로등주를 수세하여 가열 건조시켜서 주철가로등주의 표면과 주철공극에 남아 있는 수분과 공기를 강제 제거하고 등주 체온이 100~150℃로 예열된 상태에서 부식방지 피막형성제를 도포하여 고착시킴으로써 주철가로등주와 내부식성 피막제의 완전한 결합을 통해 박막형태의 부식방지피막을 형성하여 부식요인을 해소할 수 있으며 아연, 알미늄 복합피막형성제를 사용함으로써 폐수발생이 없는 무공해 공법을 채용할 수 있고 견고한 부식방지피막을 형성하게 되는 효과가 있고 부식방지 피막 위에 아크릴우레탄 도료 또는 폴리에스텔수지에 황산바륨을 혼합한 우레탄계 도료를 선택하여 피막층을 형성함으로써 우레탄계 도료에 의한 방습,방수효과와 복합피막층에 의한 피막 강도향상과 자외선 대항 효과가 높은 효과를 얻을 수 있다.In particular, the present invention fundamentally blocked the factors of heavy metals and wastewater generated in the hot dip galvanizing process by using deionized water when forming the zinc and aluminum composite coating layers, and washed and dried the cast iron street lamps by heating and drying the surface of cast iron street lamps. By removing the moisture and air remaining in the cast iron voids and applying and fixing the anti-corrosion coating agent while the column temperature is preheated to 100 ~ 150 ℃, it is possible to prevent the corrosion in the form of thin film through the perfect combination of cast iron street lamp and corrosion resistant coating agent. Corrosion factors can be eliminated by forming a film, and by using zinc and aluminum composite film forming agent, it can adopt the pollution-free method without waste water generation, and it has the effect of forming a strong anti-corrosion film. Or urethane-based mixture of barium sulfate and polyester resin By selecting a coating layer to form a coating layer, the effect of moisture-proofing and waterproofing by the urethane-based coating, and the improvement of the coating strength by the composite coating layer and the effect against UV rays can be obtained.
상기와 같은 방법으로 생산된 제품을 테스트한 결과 중금속이 검출되지 않았으며 As a result of testing the product produced by the above method, no heavy metal was detected.
염수분무시험(S.S.T)에서도 1000시간까지 녹이 발생하지 않음을 한국생산 기술연구원의 시험결과로 확인할 수 있었다.In the salt spray test (S.S.T), it was confirmed that the rust did not occur up to 1000 hours by the test results of the Korea Institute of Industrial Technology.
또한, 본 발명은 다양한 색상을 첨가하는 것이 가능하여 주위 환경에 적합한 제품을 생산할 수 있고 녹방지와 부식방지를 통해 인체와 환경에 미치는 피해를 줄일수 있는 친환경 가로등주를 제조할 수 있는 이점이 있다.In addition, the present invention is capable of adding a variety of colors to produce a product suitable for the surrounding environment, there is an advantage that can be produced environmentally friendly street lamps that can reduce the damage to the human body and environment through rust and corrosion prevention.
